Daniel Negreanu (born July 26, 1974) is a Canadian professional poker player of Romanian ancestry. He won four World Series of Poker bracelets and two World Poker Tour Championship titles. He is now ranked first in the all-time career earnings list, surpassing Phil Ivey who held that mark and is also currently the star of poker game show Million Dollar Challenge.

Negreanu is an extremely accomplished tournament and cash game player. Negreanu has amassed 4 WSOP, 2 WPT titles, numerous WSOP and WPT final tables, as well as various other tournament titles. Negreanu's most successful year came in 2004 when he was named the Card Player Player of the Year and the WSOP Player of the Year. He was also named the 2004-05 WPT Player of the Year. In 2006, Negreanu was named "Favorite Poker Player" at Card Player Magazine's Player of the Year Awards Gala.

In the past, Negreanu has regularly played the big game in Bobby's Room, in the Bellagio casino, Las Vegas, where the limits are $4,000-$8,000 or greater and the games are mixed. He is a self-admitted action junkie who always seeks new challenges and sets high goals for himself, not only at the poker table but also on the golf course. Unlike many other players, he is very outspoken about his poker results and regularly posts updates in the forums at the Full Contact Poker website. Some of Negreanu’s success is attributed to his ability to read opponents. When asked about this, Negreanu explained that the most important skill he employs is observing what hands his opponents play and how capable they are of playing them.

In December 2005, he started his own online poker cardroom "skin" site on his official site, Full Contact Poker, which also includes his blog and a variety of poker forums. He played at his cardroom under the screen name "KidPoker". In 2006, he used Full Contact Poker to launch a competition to select a protege, whom Daniel would attempt to mold into a world-class live tournament poker player. In addition, he agreed to pay the protege's entry fee into four $10,000 buy-in events. Daniel's first protege was Brian Fidler. In 2007, Daniel ran a second protege promotion, which was won by Anthony Mak.

In June 2007 Negreanu signed with PokerStars, joining Chris Moneymaker, Joe Hachem, Greg Raymer and many other professional poker players as a member of Team PokerStars. His Full Contact Poker site has since returned to being a forum and informational site.

Negreanu is currently enduring a personal bankroll building challenge on PokerStars. He started with $10 and his goal is to increase it to $100,000.
